![]() June 8, 2022: LA microelectrònica(in Catalan). At the Institute of Catalan Studies, in Barcelona. Lecture by professor Ignacio Mártil (Professor of Electronics at the Complutense University of Madrid and member of the Royal Spanish Physical Society) on "possibly the most important invention of the 20th century". May 24, 2022: El 75 aniversario del Transistor Bipolar: La invención más importante del siglo XX (in Spanish). The winning teams were announced in September 2023, an institute from Las Palmas de Gran Canaria and another from Manresa won the first prize in the categories of the competition.ĭuring 20, the years between which the anniversary of the invention is framed, we are organizing a cycle of conferences relocated to the province of Barcelona to offer different perspectives on the future, present and past of the transistor. Received proposals were from schools and institutes in Catalonia, Extremadura, the Canary Islands, the Balearic Islands and Castilla y León. The competition was open until June 30 to compulsory secondary education, baccalaureate and formative cycles, both public and private throughout the country, aimed to stimulate scientific curiosity in microelectronics among pre-university students. It is a proposal of the IMB-CNM-CSIC financed by the Fundación Española de Ciencia y Tecnología (FECYT) - Ministerio de Ciencia e Innovación. The launch coincides with the 75th anniversary of the invention of the transistor. It will reward proposals in the field of electronics and, more specifically, to the transistor as an electronic device. The IMB-CNM organizes the microelectronics contest for students Un microchip muy grandeto encourage students' interest in electronics. They are a support for actions on micro and nanoelectronics, to illustrate scientific concepts in educational centers, workshops and other events, or to create your own activities. You can find in Educational content on microelectronics all the educational materials made about chips, transistors are how a microfabrication clean room works. ![]() The center is unique in the design and manufacture of integrated circuits or simply chips, in its Micro and Nanofabrication Clean Room. This means that we are the largest center in Spain dedicated to the research and development of micro nanotechnologies and electronic microsystems, with unique capabilities in silicon technology. The IMB-CNM is the only institute in Spain capable of manufacturing transistors with full CMOS technology. The invention took place between 19, in December 1947 the experiment of physicists John Bardeen, Walter Houser Brattain and William Shockley was completed and the invention was published the following year. It is a fundamental invention for understanding the development of microelectronics in the 20th century, the miniaturization of electronic components and the digitalization processes of society. ![]() The operation of the vast majority of the equipment we use every day (televisions, audio and video players, quartz watches, cell phones, computers, LED lamps, medical equipment, electric vehicles, etc.) is based on the properties of transistors and the integrated circuits built with them. Thus, the transistor represents the physical embodiment of the '1's and '0's of binary logic on which microprocessor chips and memories are based, integrating thousands or millions of these devices in a small space. Although initially conceived as an analog amplifier device, over time its role was enhanced and its technology was adapted as a digital switch. The transistor is a semiconductor electronic device used to deliver an amplified output signal in response to an input signal and replaced the bulky and inefficient vacuum valves of the early 20th century.
